Which one of the following statements about water is FALSE?
A.Water can act both as an acid and as a base.
B.There is extensive intramolecular hydrogen bonding✓ Correct
C.Ice formed by heavy water sinks in normal water.
D.Water is oxidized to oxygen during photosynthesis.
Explanation
Water is an amphoteric oxide. Therefore, it can act as both a Bronsted- Lowry acid and a Bronsted- Lowry acid. In water, there is intermolecular H- bonding in solid, liquid and condensed state. In the given options there is intramolecular H- bonding. Ice formed by heavy water is heavier than normal water. Therefore, it sinks. In photosynthesis, oxidation of water takes place, and we get glucose and molecular oxygen as product.
